摘要: 國內菌種弱化或老化情形普遍存在於各種菇類,積極開發菌種檢定方法才能安定菇類的生產。本計畫預計蒐集國內現有的杏鮑菇的菌種,進行基本生物學特性測試、生理活性檢測與出菇試驗,建立菌種檢定標準模式。此外,開發新型菌種培養基質以期應用於菌種。本項為期三年之研究計畫旨在建立促進瓜類種苗健康活力生長之光照系統,以提供種苗業者設置人工補光設備參考,又開發促進健壯苗株生長之最佳光照技術,包含光波段、光照強度、光照時間、光照期程等參數,以減少化學矮化劑使用。同時將提供不同光照處理組合對種苗光能利用效率之資料庫,以利未來農企業發展植物工場或高精密溫室建置前之參考數據。此外,亦將配合如栽培介質、肥料、滴灌及根系周遭溫度控制等研究,以提供相搭配之栽培技術。青夏季常因颱風豪雨後,造成機械傷害與病害嚴重,導致產量大減,供貨量減少而造成價格飆漲,利用設施栽培為穩定生產之重要手段,因此須選育適合之耐熱品種。耐熱青蔥品系大量繁殖,在夏季於中南部產地進行區域試驗。選出適合夏季生產之四季蔥新品種。香菇為我國重要之菇種,年產量與產值皆是目前商業化栽培菇種中最高,但目前栽培模式主要以傳統菇舍平面化栽培,因此栽培量無法有效提升,因此本計畫擬利用環控庫間與水濂溫室建立香菇之立體化周年生產技術以提升香菇之栽培量。雲芝(Trametes versicolor或Coriolus versicolor)是一種著名藥用菌,含7種人體必需胺基酸,具增強免疫功能、提高抗病能力、強化抗氧化活性、清除自由基、抗癌細胞活性功效,隨著保健養生風氣盛行,雲芝應當可發展成養生食品。因此本計畫將研究提高雲芝栽培產能之技術,針對太空包型式或瓶栽型式在立體化栽培的模式作適切性研究。白菇英文名為White King oyster mushroom,學名為Pleurotus nerbrodensis, P. eryngii var.<EM> tuoliensis</EM>及<EM>P. eryngii</EM> var. <EM>ferulae</EM>,是一種非常珍貴的食用菌新種,其菇體潔白肥大,肉質細膩、口感脆滑。營養價值高過杏鮑菇,目前台灣並無此菇類栽培生產,而此菇在中國大陸被譽為“草原上的牛肝菌”,因此極具有開發成高級新興菇類潛力。台灣位處亞熱帶地區,要依天然氣候栽培,相當不易,因此,利用環控設備及技術研究開發以機械化、自動化產栽培瓶,以環控方式調控溫度、濕度、通風和光照,開發標準化生產技術,達到周年化生產目標,可以穩定生產出高產量、高品質的白靈菇。期望白靈菇在台灣以環控技術,達到經濟規模與效益,促進菇類產業蓬勃發展與競爭力。 </P>

<P>豌豆用途繁多,頗富經濟價值,為臺灣重要冬季蔬菜之一,產區主要集中在臺灣中部地區。目前臺灣豌豆栽培,以白粉病(Powdery mildew)為主要病害,而現有推廣之用商業品種均不抗白粉病。本研究的目地為選育出抗白粉病豌豆新品種,藉由雜交方式導入抗白粉病,以育成具抗白粉病能力,且生育旺盛,嫩莢美觀,豐產及品質優良等特性。</P>

<P>  針對轄區內主要蔬菜作物青蔥進行耐熱品種選育工作,因青蔥性喜冷涼氣候,夏季栽培不易,且近年來溫室效應日益嚴重,夏季最高溫一再攀升,再加上颱風、豪雨、乾旱等天然災害,導致青蔥價格波動不已,為保持其價格平穩,本計畫擬針對耐熱性強、豐產、品質優良等育種目標,以混合選種法選育耐熱性佳且品質優良之青蔥新品種,增加農民夏季栽培青蔥品種之選擇,推廣供農民種植,提高蔥農收益,以保持青蔥價格平穩。</P><P> </P>

Long-term dynamics investigation and analysis the nitrate contents in 1,500 vegetable samples purchased from the metropolitan areas market. It is hoped that the results of this study will promote vegetable production as well as ensure human health and safety, environmental friendliness, and sustainable operation. In this study, Pak-choi, spinach, and lettuce of the Cruciferace family were examined.</P><BR>A study on the postharvest technique of okra<BR><P class=MsoNormal 0cm 0pt; mso-layout-grid-align: none\? ; TEXT-AUTOSPACE: '><SPAN lang=EN-US mso-ascii-font-family: New mso-hansi-font-family: ' minor-fareast\?

Due to no professional nursery been established, majority of the framers propagate runner plants for their own need and as the result strawberry nursery is operated over the hot summer and often suffered from typhoon. In addition, the plant material was clonal propagated for years without renewing, growth vigor decades severely. Therefore, for solving the shortage of nursery plants. building up a production system based on the three-step propagation principles can be more important. <o:p></o:p></SPAN></P><P class=MsoNormal 0cm TEXT-INDENT: mso-char-indent-count: 0pt; ' 2.0\? 24pt;><SPAN lang=EN-US New \?Times Roman\?,serif; mso-font-kerning: 0pt'>The objective of this study is to integrate the plant factory and high-bed nursery system for strawberry runner plant production. We first renew the plant via tissue culture and propagate the first level plants in plant factory. The runner plants will be send to greenhouse high bed system for producing second levels plants before send to field high-bed system for third level production. In the previous project, we focused on the effect of cold storage of runner cuttings on nursery production. At the same time, the nursery schedule bypassed the typhoon season. The objective of this project will aim to amplify the yield potential. We will focus on the effect of container size on daughter plant quality and nursery production. The experiment will be conducted in the second and third level production. The resulted runner production and the nursery production after cold storage will be investigated. In our integrated system, we aim to stabilize the production of healthy strawberry runner plants, and the plug-grown strawberry plants will be operated 2 months before the field practice schedule. At the same time, in the purpose of avoiding detrimental environment, the farmers’ working schedule can be reorganized. <o:p></o:p></SPAN></P></SPAN></DIV></LI></OL>

<P>The plan includes strawberry and taro, both of which are important cultivated crops Miaoli area. Form strawberry nursery to transplanting period, in recent years the farmers faced shortage of the plantlets, multiple re-transplanting situation. Upgrading of cultivation techniques will reduce farmer labor and reduces the industry risk. In this year we will apply the biological fertilizer in the developed strawberry integrated management to find the best cultivation model. In miaoli county taro usually cultivated in water. With the drought take place gradually, if we develop other modes of cultivation, it will contribute to the industry. Meanwhile, taro cultivated in water often faces with soft rot and that causes additional field operations, which increase farmers labor and cost. In this study we will also conduct taro cultivation in dry land with the different cover materials to figure out the best mode.
